Enabling or disabling each of these options will complete SMPTE processing. The SMPTE processing offer power consumption levels to suit the application s features can be bypassed to support signals with other requirements. coding schemes. Multi-link UHD can be supported when multiple GS3471devices are used. The device has three other basic modes of operation which include: The GS3471 integrates Semtech s adaptive cable equalizer technology, achieving unprecedented cable lengths and SMPTE mode jitter tolerance. The device features a dual input buffer with DVB-ASI mode a 2x2 MUX. The 2x2 MUX can select between either input for Data-Through mode de-serialization and can route either of the two inputs to the The GS3471 includes an audio de-embedder and audio serial loopback independently (reclocked or clocks are internally generated.
